Roy Williams told my brother that Michael Jordan was the most competitive person he has ever been around, and it wasn't even close. George Karl told me something similar and praised Jordan for his work ethic. Jordan hated to lose and that helped fuel him to outwork people. Even if it was ping pong, golf or cards. When he left North Carolina for the NBA he was not a polished public speaker. He actually hired people help him to clean up his English and come across more professional. His combination of drive, toughness, competitiveness & athletic ability is unmatched IMHO. Shaq, Kareem & even Lebron had god given physical abilities for their size that I feel led to much of their success. The NBA is littered with 6-5 Guards who can jump. Heck Jordan had a crappy 3 Pt shot when he came out of college.
